Because the source file is redefined in the 'po/' directories, there is a
possibility that they get misaligned.
There is now a script that will check everything is in line; it is
triggered by "make check".
The case of the "util/" stuff is excluded at current time because the way
they are defined makes it hard to properly deduce the correct list of
sources, and it is not worth, the core need being on wmaker and WPrefs.

Instead of having to maintain manually the map file for LD with the list of
symbols that we want to keep in the WRaster library (the purpose is to hide
internal symbols), this patch implements a script that parses the public
API header and extracts automatically the list of names that are supposed
to be visible to the user.
The goal is to reduce possible human errors, like for example the function
RCombineAlpha that was forgotten from the list, yet still keep the map file
feature which is considered a good practice (it reduces the risk for name
clash and the risk of mis-use of internal stuff from the library).

There are a few cases in which nested functions are an helpful way to write
code, as this is explained in 'script/nested-func-to-macro.sh'. However,
some compiler do not support them (like clang), so this patch proposes an
elegant solution, where developers can get the benefit of them, but for
users they are automatically converted to C macro if needed.
The advantage of this solution is that we keep the code simple, there is no
hack in the source (like #ifdef and code duplication), yet still having the
full advantages.
The translation is done according to what have been detected by configure
(see the WM_PROG_CC_NESTEDFUNC macro) so that user has nothing to do.
